My Phone Was Working No Problem(s) All Day Wednesday About A Hour Ago I Was Tryi

to text phone no longer in service (just out of the blue) oct 2014 it expires. this is the only phone I have, its for family emergency at this moment. my father lives alone 85 years old my daughter is on her honeymoon on a cruise. no one can reach me in case of a life/death emergency right now. happens alot with my father. Assurance better have a good reason why they stopped my service without notice or a reason. I am a nervous wreck at the moment worrying about my family. Thinking about driving to my fathers 2 hrs away its 2:05 a.m. and is this safe? need answer immediately, please. cynthia (cindy) ryan (cell??) my work was suppose to call last night to let me know what time to start work. No idea, not good for my job.
